The efficacy and safety of fingolimod in patients with relapsing multiple sclerosis: A meta-analysis

Evaluation of proximod, a selective agonist of sphingosine-1-phosphate receptor-1, in healthy volunteers and patients with rheumatoid arthritis: a phase 1, double-blind, randomised, placebo-controlled, ascending dose trial

BACKGROUND

Proximod is a selective agonist of sphingosine-1-phosphate receptor-1 (S1PR1). It acts by redirecting lymphocytes from the circulation to secondary lymph nodes, and is under development as an immunomodulator for rheumatoid arthritis. We aimed to evaluate the safety, pharmacokinetics, and preliminary efficacy of proximod in healthy volunteers and patients with rheumatoid arthritis.

METHODS

We did a two part, phase 1, double-blind, randomised, placebo-controlled, ascending dose trial at a single centre in China. Eligible participants were adults aged 18-50 years with a BMI of 18-28 kg/m2 for healthy volunteers and aged 18-70 years with a BMI of 18-30 kg/m2 for patients with rheumatoid arthritis. In part 1, healthy volunteers were randomly assigned within ten cohorts to receive a single oral dose of proximod (0·125 mg, 0·25 mg, 0·5 mg, 1 mg, 1·5 mg, 2 mg, 3 mg, 5 mg, 10 mg, or 15 mg in cohorts 1-10) or placebo. In part 2, healthy volunteers were randomly assigned to receive once-daily doses of proximod 5 mg or placebo, and patients with rheumatoid arthritis were randomly assigned to receive once-daily doses of proximod 5 mg, proximod 10 mg, or placebo, for 28 days. Patients and investigators were masked to treatment assignment. The primary outcomes were safety, tolerability, and pharmacokinetic profile of proximod for 72 days in healthy volunteers and for 48 days in patients with rhematoid arthritis, assessed in all treated participants. This trial is registered with ClinicalTrials.gov (NCT06361199, NCT06361186), and is complete.

FINDINGS

Between Nov 1, 2017, and June 22, 2021, 124 healthy volunteers were randomly assigned in part 1 of the study and 124 were included in the analyses (mean age 34·3 years [SD 6·9], 62 [50%] of 124 participants were women and 62 [50%] were men, and 116 [94%] were Han Chinese ethnicity). Between Feb 16, 2022, and Oct 8, 2023, 113 participants were screened for inclusion in part 2 (80 healthy volunteers and 33 patients with rheumatoid arthritis). 79 participants were excluded and 34 were randomly assigned (10 healthy participants and 24 patients with rheumatoid arthritis), 34 of whom were included in the analyses. Ten (100%) of ten healthy participants were Han Chinese ethnicity, with a mean age of 39·9 years (SD 7·3). Five (50%) of ten healthy volunteers were women and five (50%) were men). 22 (92%) of 24 participants with rheumatoid arthritis were Han Chinese ethnicity, with a mean age of 52·7 years (SD 6·8). 22 (92%) of 24 patients with rheumatoid arthritis were women and two (8%) were men. In part 1, all doses of proximod were well tolerated, with no dose-related adverse reactions or serious adverse events observed. In part 2, 74 adverse reactions were reported in eight (80%) of ten healthy volunteers and 22 (92%) of 24 patients with rheumatoid arthritis. Adverse events associated with proximod were predominantly mild or moderate. In part 2, the concentration of proximod and its active metabolite, proximod-phosphate, gradually increased in all three groups receiving proximod and the EC50 of the S1PR1 agonist for proximod-phosphate (6·1 ng/mL) was reached on day 14 for both 5 mg groups, and on day 7 for the 10 mg group. The mean Ctrough values for proximod-phosphate on day 28 were 7·7 ng/mL and 10·2 ng/mL for 5 mg in healthy volunteers and patients with rheumatoid arthritis, respectively, and 15·3 ng/mL for 10 mg in patients with rheumatoid arthritis. In patients with rheumatoid arthritis, lymphocyte count decreased after treatment in all proximod groups reaching nadir at approximately day 28, with a corresponding percentage decline from baseline of 65·25% in the 5 mg group, 71·64% in the 10 mg group, and 20·57% in the placebo group.

INTERPRETATION

Proximod exhibited good tolerability over the 28-day treatment period, demonstrating its potential in reducing blood lymphocyte count. These results highlight the promise of the S1PR1 agonist proximod as a potential candidate for rheumatoid arthritis treatment, warranting further investigation in subsequent clinical studies.

Safety of fingolimod in patients with relapsing remitting multiple sclerosis: A descriptive analysis of data from the EudraVigilance database

The most prevalent disease course of Multiple Sclerosis (MS) is relapsing remitting multiple sclerosis (RRMS). Fingolimod (Gilenya®) was the first oral disease-modifying therapy to RRMS. Patients affected by MS require long-term treatment, making the ongoing evaluation of the safety profile of fingolimod imperative. The aim of this study was to analyze the post-marketing pharmacovigilance data of fingolimod in Europe. Data of 12-year period (1 January 2011-19 June 2023) were obtained from EudraVigilance, and a descriptive analysis using drug-reaction pairs was performed. A total of 22,957 reports were collected. The most reported adverse events (AEs) were related to nervous system disorders SOC (multiple sclerosis relapse n = 2271; 3.51%, headache n = 921; 1.42%, central nervous system lesion n = 893; 1,38%, dizziness 769; 1,19%, hypoaesthesia 487; 0.75% and multiple sclerosis 449; 0.69%), followed by investigations (lymphocyte count decreased n = 1648; 2.55%, white blood cell count decreased n = 833; 1.29%), blood and lymphatic system disorder (lymphopenia n = 1146; 1.77%), and general disorders and administration site condition (fatigue n = 1106; 1.71%, gait disturbance 564; 0.87%). A percentage of 23.00% of serious adverse events (SAEs), among the most reported were multiple sclerosis relapse (n = 2271; 15.27%), macular oedema (n = 793; 5.33%), bradycardia (n = 678; 4.56%), leukopenia (n = 533; 3.58%), and multiple sclerosis (n = 449; 3.02%). Most of AEs were non-serious, some SAEs related to cardiac, ophthalmic and infectious disorders emerged: their prevalence, along with the alignment of reported AEs with existing literature, supports the overall safety of fingolimod. Considering the rare and long-term ADRs that may arise in patients chronically treated for MS, continuous pharmacovigilance remains essential.

The Impact of Neuroimmunologic Disease and Developing Nervous System

Over the last two decades, neuroimmunologic disorders of childhood have been increasingly described, phenotyped, and treated. These disorders remain rare in the general population and while sharing common therapeutic interventions due to their immune pathophysiology, are heterogeneous with regard to presentation and risk of recurrence. As such, the impact of these disorders on the developing brain has come into the forefront of emerging research in pediatric neuroimmunology. Investigations into the singular impact of monophasic disease on long-term development and the impact of early and aggressive disease-modifying therapy in relapsing conditions are quickly becoming areas of ripe investigation as the field's most optimal way to treat and monitor these conditions over time. Although critically important in evaluating the developing brain, research has been heterogeneous among these diseases and limited by small cohort size. This narrative review details the role of common neuroimmunologic disorders in long-term neurological and cognitive outcomes in children as they develop.

A decade of fingolimod in multiple sclerosis: Insights from a large real-world cohort study

BACKGROUND AND OBJECTIVES

Ten years after its authorization, data about fingolimod use in real-world setting is still scarce. Here we describe the long-term evolution of fingolimod-treated relapsing-remitting MS (RRMS) patients and determine baseline characteristics associated with risk of relapses or disability.

METHODS

We analyzed baseline characteristics and clinical evolution of 1227 patients with RRMS treated with fingolimod from 2010 to 2019 in 4 French MS referral centers. We used Cox models to determine risks factors of relapses and sustained EDSS worsening.

RESULTS

Median follow-up duration was 50 months, and 63% of patients remained fingolimod-treated at the end of follow-up. Mean 5-years annualized relapse rate (ARR) decreased from 0.63 (0.60-0.67) to 0.26 (0.24-0.29, P<0.001), while the mean EDSS rose from 2.5 (2.4-2.6) to 3.0 (2.8-3.1, P<0.001). Female sex, lower age, higher EDSS and use of natalizumab were associated with relapse risk. Female sex was associated with sustained EDSS increase risk.

CONCLUSIONS

Based on a large real-world cohort, our results confirm the durable reduction of the ARR described in pivot studies. Switching from moderate-efficacy DMT to fingolimod decreased the relapse risk. Switching patients from high-efficacy DMT increased risk of relapse, but the overall five-years ARR remained stable.

Leptomeningeal enhancement under different MS immunotherapies: A monocentric retrospective cohort study of 214 patients

BACKGROUND

Leptomeningeal inflammation in patients with multiple sclerosis (MS) mainly affects meningeal B-cell follicle-like structures linked to cortical and subpial lesions and can be visualized as leptomeningeal enhancement (LME).

OBJECTIVE

To evaluate the evolution of LME under different MS immunotherapies.

METHODS

A total of 214 MS patients treated with anti-CD20 therapies or fingolimod at the university hospital Bern were screened for LME. Magnetic resonance imaging (MRI) and medical records were retrospectively evaluated, and comparative statistics were applied.

RESULTS

We compared MS patients treated with anti-CD20 therapies (128 patients (59.8%)) or fingolimod (86 patients (40.2%)). Of 128 anti-CD20-treated patients, 108 (84.4%) had no LME, 11 (8.6%) had persistent LME, and 9 (7.0%) showed resolution of LME. Of 86 fingolimod-treated MS patients, 81 (94.2%) had no LME and 5 (5.8%) persistent LME. Patients with LME persistence were older than those without or resolution of LME (p = 0.039). Resolution of LME was more frequent during anti-CD20 compared with fingolimod treatment (p = 0.019).

CONCLUSION

We observed LME resolution under treatment with anti-CD20 therapies. As LME might play an important role in cerebral gray matter pathology in MS, further investigations including extensions to higher field strengths, correlation with clinical phenotypes, and comparison with other immunotherapies are needed.

Assessment of Functional Capacity of Immune System in Patients with Multiple Sclerosis using QuantiFERON Monitor

Background

The QuantiFERON®-Monitor (QFM) is an assay that measures interferon-γ production and was developed to provide an objective marker of complex immune response. In this study, we evaluated the use of the QFM test in patients with two forms of multiple sclerosis (MS), relapsing-remitting form treated with fingolimod (fMS) and secondarily progressive form not treated pharmacologically (pMS), and in healthy controls (HC). We hypothesized that IFN-γ levels would be lower in those subjects who are relatively more immunosuppressed and higher in those with normal or activated immune function.

Methods

This single-center observational study was conducted from November 2020 to October 2021 and compared results in three groups of patients: 86 healthy controls, 96 patients with pMS, and 78 fMS. Combination of lyophilized stimulants was added to 1 ml heparinized whole blood within 8 hr of collection. Plasmatic IFN-γ was measured using the ELISA kit for the QFM and data were obtained in IU/ml.

Results

The results showed that controls had nearly 2-fold higher levels of IFN-γ (QFM score) in median (q25, q75) 228.00 (112.20, 358.67) than the MS patient groups: pMS 144.80 (31.23, 302.00); fMS 130.50 (39.95, 217.07) which is statistically significant difference P-value: HC vs. pMS = 0.0071; HC vs. fMS = 0.0468. This result was also confirmed by a validation analysis to exclude impact of variable factors, such as disease duration and Expanded Disability Status Scale scores.

Conclusions

Results showed that controls had higher levels of IFN-γ production than the MS patient groups and suggest that MS patients included in this study have a lower ability of immune system activation than HC. Results confirm that fingolimod is able to suppress production of IFN-γ. The fact that the QFM score of MS patients is significantly lower than that of HC may indicate a dysfunctional state of the immune system in baseline conditions.

Fingolimod effects on the brain are mediated through biochemical modulation of bioenergetics, autophagy, and neuroinflammatory networks

Fingolimod (FTY720) is an oral drug approved by the Food and Drug Administration (FDA) for management of multiple sclerosis (MS) symptoms, which has also shown beneficial effects against Alzheimer's (AD) and Parkinson's (PD) diseases pathologies. Although an extensive effort has been made to identify mechanisms underpinning its therapeutic effects, much remains unknown. Here, we investigated Fingolimod induced proteome changes in the cerebellum (CB) and frontal cortex (FC) regions of the brain which are known to be severely affected in MS, using a tandem mass tag (TMT) isobaric labeling-based quantitative mass-spectrometric approach to investigate the mechanism of action of Fingolimod. This study identified 6749 and 6319 proteins in CB and FC, respectively, and returned 2609 and 3086 differentially expressed proteins in mouse CB and FC, respectively, between Fingolimod treated and control groups. Subsequent bioinformatics analyses indicated a metabolic reprogramming in both brain regions of the Fingolimod treated group, where oxidative phosphorylation was upregulated while glycolysis and pentose phosphate pathway were downregulated. In addition, modulation of neuroinflammation in the Fingolimod treated group was indicated by upregulation of retrograde endocannabinoid signaling and autophagy pathways, and downregulation of neuroinflammation related pathways including neutrophil degranulation and the IL-12 mediated signaling pathway. Our findings suggest that Fingolimod may exert its protective effects on the brain by inducing metabolic reprogramming and neuroinflammation pathway modulation.

Cost-effectiveness analysis of rituximab versus natalizumab in patients with relapsing remitting multiple sclerosis

Introduction

Multiple sclerosis (MS) is an inflammatory disease in which the myelin sheaths of the nerve cells in the brain and spinal cord, which are responsible for communication, are destroyed and cause physical signs and symptoms. According to studies, anti-CD20 monoclonal antibodies have significant results in the treatment of this disease. Thus, the aim of the present study was to determine the cost-effectiveness of rituximab against natalizumab in the patients with RRMS in southern Iran in 2020.

Methods

This is an economic evaluation including cost-effectiveness analysis in which the Markov model with a lifetime horizon was used. The study sample consisted of 120 patients randomly selected from among those referred to the MS Association and the Special Diseases Unit of Shiraz University of Medical Sciences. In this study, the costs were collected from a societal perspective, and the outcomes were obtained in the form of Quality Adjusted Life Years (QALY) and the mean relapse rate. The TreeAge pro 2020 and Excel 2016 software were used for data analysis.

Results

The comparative study of rituximab and natalizumab showed that the patients receiving rituximab had lower costs ($ 58,307.93 vs. $ 354,174.85) and more QALYs (7.77 vs. 7.65). In addition, the incidence of relapse by rituximab was lower compared to natalizumab (1.15 vs. 2.57). The probabilistic one-way sensitivity analysis showed the robustness of the results. The scatter plots also showed that rituximab was more cost-effective for the patients in 100% of the simulations for the threshold of < $ 37,641.

Discussion and conclusion

According to the results of this study, rituximab had higher cost-effectiveness than natalizumab. Therefore, it could be a priority for RRMS patients compared to natalizumab because it reduced treatment costs and increased effectiveness.

Risk for Cardiovascular Adverse Events Associated With Sphingosine-1-Phosphate Receptor Modulators in Patients With Multiple Sclerosis: Insights From a Pooled Analysis of 15 Randomised Controlled Trials

Background

All agents engaging sphongosine-1-phospate receptors (S1PRs) will have some cardiovascular effect. This study aimed to elucidate the risk of cardiovascular adverse events (AEs) in patients with multiple sclerosis (MS) treated with S1PR modulators (S1PRMs).

Methods

We systematically searched the PubMed, EMBASE, and Cochrane Library databases for randomised controlled trials (RCTs) published through January 5, 2021. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated using the random-effects model. Sensitivity analyses and meta-regression were performed.

Results

Seventeen RCTs (12 for fingolimod; 3 for ozanimod; 2 for siponimod) involving 13,295 patients were included. Compared with the control treatment, S1PRMs significantly increased the risk of cardiovascular AEs (RR, 2.21; 95% CI, 1.58–3.10; I², 75.6%). Notably, the high-risk cardiovascular AEs associated with S1PRMs were primarily bradyarrhythmia (RR, 2.92; 95% CI, 1.91–4.46; I², 30.8%) and hypertension (RR, 2.00; 95% CI, 1.49–2.67; I², 56.5%). Subgroup analysis results were consistent with the primary outcomes except that ozanimod was associated with a higher risk of hypertension only (RR, 1.76; 95% CI, 1.10–2.82; I², 0.0%), while siponimod was associated with a higher risk of bradyarrhythmia only (RR, 2.75; 95% CI, 1.75–4.31; I², 0.0%). No significant inter-subgroup differences were observed (P_interaction > 0.05).

Conclusions

S1PRM use increased the risk of cardiovascular AEs by 1.21 times in patients with MS, and increased risks for bradyarrhythmia and hypertension were at 2.92- and 2.00-fold, respectively. These findings can help clinicians assess the risk of cardiovascular AEs in patients treated with S1PRMs.

Different Doses of Fingolimod in Relapsing-Remitting Multiple Sclerosis: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background: The efficacy and safety of fingolimod for relapsing-remitting multiple sclerosis (RRMS) had been well verified in several large randomized controlled trials (RCTs) during the past decade. However, there are fewer systematic comparisons of different doses of fingolimod and whether the dose of 0.5 mg/d is the optimal one still remains to be solved. Objective: The objective of this systematic review was to evaluate the efficacy and safety of the four existing doses of fingolimod in the treatment of RRMS, especially the dose of 0.5 mg/d. Methods: MEDLINE, EMBASE, Cochrane Library, and clinicaltrials.gov were searched for RCTs which were performed to evaluate different doses of fingolimod and the corresponding control (placebo or DMTs) up to October 2020. Review Manager 5.3 software was used to assess the data. The risk ratio (RR) and mean difference (MD) was analyzed and calculated with a random effect model. Results: We pooled 7184 patients from 11 RCTs. Fingolimod 0.5 mg/d was superior to control group in all eight efficacy outcomes including annualized relapse rate (ARR) (MD -0.22, 95%CI -0.29 to -0.14, p < 0.00001) but surprisingly showed a higher risk of basal-cell carcinoma (RR 4.40, 95%CI 1.58 to 12.24, p = 0.004). Although 1.25 mg/d is more than twice the dose of 0.5 mg/d, the effect size was almost similar between them. Dose of 5 mg/d obtained an unsatisfactory efficacy while showing a greater risk of adverse events than other three doses (RR 1.17, 95%CI 1.05 to 1.30, p = 0.003). Additionally, fingolimod 0.25 mg/d not only showed a better performance in delaying the disease progress of magnetic resonance imaging (MRI), but also achieved a certain degree of patient treatment satisfaction. Conclusion: At present, 0.5 mg/d remains to be the optimal dose of fingolimod for RRMS patients but trials of a lower dose are still of great clinical significance and should be paid more attentions.

Incidence and Risk of Infection Associated With Fingolimod in Patients With Multiple Sclerosis: A Systematic Review and Meta-Analysis of 8,448 Patients From 12 Randomized Controlled Trials

Background and Aims: There is a controversy regarding whether fingolimod is associated with an increased risk of infection in patients with multiple sclerosis (MS). We performed a systematic review and meta-analysis of data from randomized controlled trials (RCTs) to determine the risk of infection in these patients.

Methods: We systematically searched PubMed, EMBASE, the Cochrane Library, and clinicaltrials.gov from inception to April 8, 2020, to identify RCTs that reported the occurrence of infection in patients with MS treated with fingolimod. Relative risks (RRs) and 95% confidence intervals (95% CIs) were calculated using the random-effects model.

Results: Twelve RCTs including 8,448 patients were eligible. Compared with the control (placebo and other active treatments), fingolimod significantly increased the risk of infection (RR, 1.16; 95% CI, 1.07–1.27; I², 81%), regardless of whether the infection was a general infection (RR, 1.14; 95% CI, 1.05–1.25; I², 78%), or a serious infection (RR, 1.49; 95% CI, 1.06–2.10; I², 0%). Analyses of subgroups found that fingolimod significantly increased the risk of lower respiratory infection (RR, 1.48; 95% CI, 1.19–1.85; I², 0%) and herpes virus infection (RR, 1.34; 95% CI, 1.01–1.78; I², 9%). There appears to be no dose-dependent increase in the risk of infection associated with fingolimod (0.5 mg: RR, 1.15; 95% CI, 1.07–1.25; I², 91%; 1.25 mg: RR, 1.11; 95% CI, 0.97–1.28; I², 81%; P_interaction = 0.66).

Conclusions: Compared with a placebo and other active treatments, fingolimod was associated with a 16% increase in the risk of infection, especially lower respiratory infection and herpes virus infection. The risk of infection associated with fingolimod might not be dose related.

Approaching coronavirus disease 2019: Mechanisms of action of repurposed drugs with potential activity against SARS-CoV-2

On March 11, 2020, the World Health Organization (WHO) declared the severe acute respiratory syndrome caused by coronavirus 2 (SARS-CoV-2) a global pandemic. As of July 2020, SARS-CoV-2 has infected more than 14 million people and provoked more than 590,000 deaths, worldwide. From the beginning, a variety of pharmacological treatments has been empirically used to cope with the life-threatening complications associated with Corona Virus Disease 2019 (COVID-19). Thus far, only a couple of them and not consistently across reports have been shown to further decrease mortality, respect to what can be achieved with supportive care. In most cases, and due to the urgency imposed by the number and severity of the patients' clinical conditions, the choice of treatment has been limited to repurposed drugs, approved for other indications, or investigational agents used for other viral infections often rendered available on a compassionate-use basis. The rationale for drug selection was mainly, though not exclusively, based either i) on the activity against other coronaviruses or RNA viruses in order to potentially hamper viral entry and replication in the epithelial cells of the airways, and/or ii) on the ability to modulate the excessive inflammatory reaction deriving from dysregulated host immune responses against the SARS-CoV-2. In several months, an exceptionally large number of clinical trials have been designed to evaluate the safety and efficacy of anti-COVID-19 therapies in different clinical settings (treatment or pre- and post-exposure prophylaxis) and levels of disease severity, but only few of them have been completed so far. This review focuses on the molecular mechanisms of action that have provided the scientific rationale for the empirical use and evaluation in clinical trials of structurally different and often functionally unrelated drugs during the SARS-CoV-2 pandemic.

Clinical effectiveness of reduced fingolimod dose in relapsing remitting multiple sclerosis-a Portuguese cohort

BACKGROUND

Fingolimod is an oral daily treatment for relapsing remitting multiple sclerosis (RRMS). A decrease in lymphocytes count is a common side effect, whereby clinicians occasionally propose a reduced dose rather than its discontinuation. However, current data on the effectiveness of these regimens are scarce and contradictory. Our objective was to investigate if the fingolimod effectiveness is maintained with reduction in dosing frequency.

METHODS

Retrospective and observational study of RRMS patients taking fingolimod-nondaily (FTY-ND) for at least 6 months. Propensity score-based matching was performed to select patients taking daily dose (FTY-ED) with comparable baseline characteristics: age, sex, disease duration, annualized relapse rate (ARR), and expanded disability status scale (EDSS). Afterwards, clinical and laboratorial assessment was evaluated in both groups.

RESULTS

Thirty-six patients were included in each group (FTY-ED vs. FTY-ND). Decrease in lymphocytes count was the main reason for switching to FTY-ND (88.9%). Previous treatment with natalizumab was inversely associated with risk of reducing dose (OR 0.253, 95%CI = 0.08-0.807, p = 0.016). There were no significant differences in clinical disease activity between patients FTY-ED vs. FTY-ND: mean ARR 0.4 vs. 0.3 (p = 0.247), median EDSS 2.0 vs. 2.0 (p = 0.687), and proportion of patients with EDSS increase 8.3% vs. 13.9% (p = 0.453). FTY-ND was overall well tolerated and was associated with an increase in the mean lymphocytes count (362 ± 103 cells/mm³ to 541 ± 183 cells/mm³, p < 0.001).

CONCLUSION

These data suggest that the effectiveness of FTY is maintained despite the reduction of the dose, minimizing the most common adverse events. These findings warrant further confirmation, ideally with randomized clinical trials.

The efficacy and safety of fingolimod in patients with relapsing multiple sclerosis: A meta-analysis

AIMS

The aim of the present meta-analysis was to evaluate the efficacy and safety of fingolimod in patients with relapsing multiple sclerosis (RMS).

METHODS

PubMed, Embase, the Cochrane Library and ClinicalTrials.gov were searched for relevant studies. Two authors independently selected the studies, assessed the risk of bias, and extracted the data. The meta-analysis was performed in RevMan 5.3 provided by the Cochrane Collaboration.

RESULTS

Ten studies met the inclusion criteria. In patients with RMS, fingolimod demonstrated a significantly lower annualized relapse rate (0.5 mg/d: mean difference [95% confidence interval] = -0.22 [-0.29 to -0.14]; 1.25 mg/d: -0.26 [-0.36 to -0.16]; 5 mg/d: -0.41 [-0.72 to -0.10]) than placebo. Fingolimod also exhibited a favorable performance on other magnetic resonance imaging outcomes and improved the quality of life in patients. No significant difference was noted in the prevalence of adverse events between the fingolimod treatment group and the placebo/disease-modifying therapy groups.

CONCLUSIONS

Fingolimod may offer benefits for RMS patients and presents an acceptable safety profile.
